| 摘 要： | 传统的湿度测量需要设计转换电路，并要经过复杂的校准、标定过程，应用不方便．瑞士Sensirion公司生产的新型数字式温湿度传感器SHTxx采用独特的CMOSens技术，将湿敏元件、测温元件、A／D转换器以及串行接口电路集成在一个芯片中，具有体积小、功耗低、高可靠性、免外围电路及全互换的特点．微处理器通过二线串口与SHTxx进行通信，该接口与12C接口不兼容．利用SHTxx可以方便地与单片机组成温湿度测量装置．

| Abstract: | Traditional measurement of humidity needs conversion circuit, which should be calibrated and tested within accuracy, so its application is very inconvenient. The new generation digital temperature and humidity sensor SHTxx is produced by Swiss Sensirion Inc based on unique CMOSens technology. A relative humidity sensor, a temperature sensor, an analog to digital converter and a serial interface circuit are integrated on the same chip SHTxx. The sensor has the characteristics of tiny size, low power, high relia- bility, exemption of peripheral circuit and full-interchange. Microprocessor can communicate with SHTxx by the serial interface of two wires which is not compatible with I2C interfaces. Using SHTxx and MCU, the design of the measuring equipment is simply given. |
